If you selected RTK Float or RTK Fixed, adjust the following RTK
Parameters settings:
• Select Extrapolation or Delay.
– Extrapolation is for low-latency, high frequency output (>= 5 Hz)
RTK applications. The rover will extrapolate the base station’s
carrier phase measurement corrections when computing the rover's
current RTK position.
– Delay is for 1 Hz high precision RTK applications. The Rover
RTK engine will compute either a delayed RTK position (for the
epoch to which the newly received RTCM/CMR message
corresponds) or the current stand-alone position (while waiting for
new RTCM/CMR messages coming from the base).
• Select the Dynamics of the antenna status during RTK, either Static
or Kinematic.
• Specify the Ambiguity fixing level. The Ambiguity Fixing Level
radio buttons govern the process of the RTK engine fixing integer
ambiguities. The RTK engine uses the ambiguity fix indicator when
making decision whether to fix ambiguities or not. Low, Medium,
and High correspond to the indicator's 95%, 99.5% and 99.9%
states, respectively. The higher the specified confidence level, the
longer the integer ambiguity search time
6.Select the
Ports
tab and set the following parameters for Serial port C
